[0001] The invention relates to the technical field of gloves, in particular to an anti-slip labor protection glove core and a preparation process thereof. Background Art

[0002] The glove core usually refers to the inner layer or internal structure of the glove. The labor protection glove core is usually made of soft, sweat-absorbent and breathable materials to ensure that the wearer feels comfortable during long-term use.

[0003] Patent publication number CN214432107U was retrieved and disclosed a breathable labor protection glove, belonging to the field of gloves, including a glove body, a ventilation device on the glove body, the ventilation device including a shell and a piston, a ventilation cavity is arranged in the shell, the piston is slidably connected in the ventilation cavity, the ventilation cavity connects the internal space of the glove body with the external space, and a power device for the reciprocating movement of the piston is arranged on the shell. The present invention achieves the effect of ventilating the inside of the glove body through the ventilation device that can exchange the air in the internal space of the glove body with the air in the external space. The user only needs to pull the drawstring to make the piston move back and forth in the ventilation cavity under the action of the power device, which is convenient and quick to use.

[0004] This patented technology has the advantage of good air permeability when used, but there are still shortcomings when used. During the use of the labor protection glove core, the specifications of the wrist cannot adapt to the needs of different people, resulting in the wrist being too loose, affecting the firmness of wearing, and easily detaching and causing severe wear on the skin. For this reason, we propose an anti-slip labor protection glove core and its preparation process to solve the existing problems. Summary of the invention

[0005] The purpose of the present invention is to provide a non-slip labor protection glove core and a preparation process thereof in view of the problems existing in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: a non-slip labor protection glove core and a preparation process thereof, comprising a glove core body, a closing structure and a pressurizing structure,

[0007] The glove core body comprises a wrist opening, and the wrist opening and the interior of the glove core body are interconnected;

[0008] The closing structure includes a ring-shaped air bag located inside the wrist opening, and a Velcro body is provided at the joint between the air bag and the wrist opening;

[0009] The pressurizing structure includes an air intake pipe running through the upper end of the airbag, a valve core located inside the upper end of the air intake pipe, a valve seat and a support ring 1 located on the upper and lower sides of the valve core, and a spring fixed at the lower end of the valve core and connected to the upper end of the support ring 1.

[0010] Preferably, the inner wall corners of the glove core body are all provided with a latex layer. The fit between the stitched corners of the glove core body and the skin is improved by the flexible fit of the latex layer, so that the comfort is improved.

[0011] Preferably, both upper and lower ends of the glove core body are provided with a rubber layer, the rubber layer is in a crisscross grid pattern, and anti-slip patterns are provided at the intersection of the grid pattern. The rubber layer improves the firmness of grasping objects, and the anti-slip patterns improve the anti-slip during grasping, and the anti-slip patterns reduce the impact of the rubber layer on the bending flexibility of the gloves.

[0012] Preferably, the Velcro body comprises a sub Velcro and a mother Velcro, the sub Velcro is located outside the airbag, the mother Velcro is located on the inner wall of the wrist opening, and the sub Velcro and the mother Velcro are bonded to each other. The airbag is bonded and installed through the Velcro body, which is convenient for installation on the inner wall of the wrist opening.

[0013] Preferably, the inner wall of the wrist opening is provided with a ring-shaped rubber band, which plays a role of tightening the wrist opening.

[0014] Preferably, a mouthpiece is provided at the upper end of the air inlet pipe, the mouthpiece is connected to the air inlet pipe, and the air inlet pipe is in the shape of a bellows. The mouthpiece is used when a person blows through the mouth, and the bellows structure facilitates the bending of the air inlet pipe.

[0015] Preferably, the upper end of the valve core is conical, the upper end of the valve core is located inside the valve seat, a through groove is provided inside the upper end of the wrist opening, and the air intake pipe is located inside the pipe groove. The valve core is closed to the opening of the valve seat by elastic support of a spring, the through groove is used for the installation of the air intake pipe, and through the bellows structure, the air intake pipe shell is bent and placed flat to be accommodated inside the through groove.

[0016] Preferably, a filter element is provided at the lower end of the valve seat. The filter element usually contains hydrophilic or hygroscopic materials, such as activated carbon, silica gel or porous ceramics. The surfaces of these materials have a large number of micropores and a high specific surface area, and can capture water vapor molecules through adsorption on their surfaces and pores. When air passes through the filter element, the water vapor in it will be adsorbed by the material of the filter element, so that the water vapor content in the air is reduced. The presence of water vapor may affect the pressure and stability of the gas inside the airbag, thereby reducing the expansion speed and expansion effect of the airbag, and even affecting its normal deployment. The filter element adsorbs the water vapor passing through the inlet tube.

[0017] Preferably, the lower end of the filter element is provided with a second support ring connected to the inside of the air inlet pipe. The second support ring supports the lower end of the filter element, and the filter element is fixed between the second support ring and the first support ring.

[0018] Preferably, the steps of preparing the core of the labor protection gloves are as follows:

[0019] S1: Use polyester fiber, cotton, and nylon materials as raw materials for the glove core. Polyester fiber, cotton, and nylon materials have the characteristics of softness, moisture absorption, and breathability. Cut and pre-treat the selected raw materials to meet the size and shape requirements of the glove core. Use a sewing machine to sew the cut materials into the internal structure of the glove core. Coat the interface of the inner wall with hot-melt latex, and let it stand to cool and form, so that a cold medium can be reflected during cooling and forming, thereby shortening the cooling and forming time.

[0020] S2: After the main body of the glove core is formed, one end is adhered to the hot-melt non-slip rubber compound, impregnated, and cooled to form. One or both sides can be impregnated as needed to increase the friction with the surface of the object when using it to grip and improve the non-slip property.

[0021] S3: At the same time, the adhesive material is coated on the inner wall of the wrist opening, the mother Velcro is adhered, which is used for the adhesion of the child Velcro, and the outer wall of the airbag is adhered to the mother Velcro through the child Velcro. The airbag is flexibly attached to the wrist strap. It is worth mentioning that when the bowl mouth is edging, pure cotton fabric is used, and the rubber band is wrapped inside the pure cotton fabric to apply an elastic force to tighten the wrist inward. The cotton edging causes less wear on the skin and has good breathability.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention provides an airbag at the wrist opening of the protective gloves core, which fits the inner wall of the wrist opening and is located on the outer side of the wrist of the person wearing the protective gloves, thereby avoiding the problem that the hemming at the wrist opening of the protective gloves core is loose and the hemming material is rough, which causes great wear on the wrist during use. The airbag fits the hand softly and is more comfortable to wear;

[0024] 2. When the wearer's wrist cannot be fitted, the pressurized structure is used to pressurize the inside of the airbag by blowing it up, so that the airbag swells up and fits firmly on the wrist, making the labor protection gloves tight to wear and suitable for the wearing needs of people of different thicknesses.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 9 , the present invention provides three embodiments:

[0040] Embodiment 1:

[0041] A non-slip labor protection glove core and a preparation process thereof, comprising a glove core body 100, a closing structure 200 and a pressurizing structure 300.

[0042] The glove core body 100 includes a wrist opening 103, and the wrist opening 103 and the interior of the glove core body 100 are interconnected;

[0043] The inner corners of the glove core body 100 are all provided with latex layers 104 .

[0044] The upper and lower ends of the glove core body 100 are both provided with a rubber layer 101 , the rubber layer 101 is in a crisscross grid shape, and anti-slip patterns 102 are provided at the intersections of the grids.

[0045] The upper and lower ends of the glove core body 100 are provided with a rubber layer 101, so that the glove core has better wear resistance and durability, prolongs the service life and reduces the replacement frequency. The inner setting of the latex layer 104 helps to reduce the direct contact between the skin and other materials and avoid the problem of large wear on the skin at the inner seams. By arranging a criss-cross grid pattern on the rubber layer 101 and arranging anti-slip patterns 102 at the intersection thereof, the grip and operational stability of the gloves can be effectively increased, and the displacement or sliding of the gloves during work can be reduced.

[0046] Embodiment 2:

[0047] The closing structure 200 includes a ring-shaped air bag 201 located inside the wrist opening 103, and a Velcro body 204 is provided at the joint between the air bag 201 and the wrist opening 103;

[0048] The Velcro body 204 includes a sub-Velcro and a mother Velcro. The sub-Velcro is located on the outside of the airbag 201 , and the mother Velcro is located on the inner wall of the wrist opening 103 . The sub-Velcro and the mother Velcro are bonded to each other.

[0049] The inner wall of the wrist opening 103 is provided with a ring-shaped rubber band 202 .

[0050] By setting the sub-velcro and the main Velcro, the airbag 201 of the closing structure 200 can be conveniently installed, and can be recycled after the glove core body 100 is worn. When the airbag 201 is not needed, the wrist opening 103 can be rolled outward, and the main Velcro is folded outward to avoid contact with the skin. At the same time, the rubber band 202 tightens the folded wrist opening 103, and it can be used flexibly according to needs. The used materials can be recycled and reused, which reduces the waste of resources and reduces the use cost:

[0051] The design of the airbag 201 in the closing structure 200 and the rubber band 202 inside the wrist opening 103 can provide better fit. The Velcro body 204 is arranged at the joint between the airbag 201 and the wrist opening 103 to ensure that the closing structure 200 will not be accidentally loosened during work, so that the glove fits the wrist of the wearer more closely, increases the protection and comfort of use, reduces the pressure caused by the wearer wearing the gloves for a long time, and reduces the fatigue of the hands.

[0052] The reason why the sub-Velcro and the mother Velcro can be bonded is mainly because they use a special material, namely nylon. Nylon is a common synthetic polymer that is widely used in the manufacture of various types of fabrics, wires and synthetic materials due to its good mechanical properties, wear resistance and tension resistance. In Velcro, nylon is usually made into tiny hook-like structures so that they can adhere to each other when they are fitted. The special fiber structure of nylon allows the sub-Velcro and the mother Velcro to adhere to each other when they are in contact, forming a separable but strong connection. When the sub-Velcro contacts the mother Velcro, the tiny hook-like structure can penetrate and entangle the ring structure, forming a close physical connection. Since this connection method does not involve adhesives or bonding agents, it is not easy to cause the problem of viscosity loss after repeated use.

[0053] Embodiment three:

[0054] The pressurizing structure 300 includes an air inlet pipe 302 passing through the upper end of the airbag 201, a valve core 304 located inside the upper end of the air inlet pipe 302, a valve seat 303 and a support ring 305 located on the upper and lower sides of the valve core 304, and a spring 308 fixed to the lower end of the valve core 304 and connected to the upper end of the support ring 305.

[0055] A mouthpiece 301 is provided at the upper end of the air inlet pipe 302 , and the mouthpiece 301 is communicated with the air inlet pipe 302 , which is in the shape of a corrugated tube.

[0056] The upper end of the valve core 304 is conical, and the upper end of the valve core 304 is located inside the valve seat 303. A through groove 203 is opened inside the upper end of the wrist opening 103, and the air inlet pipe 302 is located inside the pipe groove.

[0057] A filter element 307 is disposed at the lower end of the valve seat 303 .

[0058] A second support ring 306 connected to the inside of the air inlet pipe 302 is provided at the lower end of the filter element 307 .

[0059] In the glove core body 100, the airbag 201 is usually made of soft and wear-resistant rubber or silicone material. In addition to being elastic and wear-resistant, these materials can also maintain good sealing to prevent leakage after inflation. When the user puts on the gloves, the airbag 201 is in a deflated state and in contact with the skin. When inflation is required, the airbag 201 is filled with air. As the pressure in the airbag 201 increases, its material will gradually expand and fit tightly to the surface of the hand skin, forming a stable support that conforms to the curve of the hand. The inflated airbag 201 can provide additional support and cushioning for the hand, reducing the discomfort caused by wearing gloves for a long time. Since the airbag 201 fits the skin more closely, the flexibility and operability of the hand are enhanced, which helps to reduce the inconvenience of operation caused by the gloves being too stiff. The design of the airbag 201 in the glove can effectively achieve stable support and comfortable fit for the hand, improve the flexibility and comfort of the hand, and allow the wearer to perform various operations more freely at work;

[0060] When the airbag 201 does not fit the skin, the person holds the mouthpiece 301 and blows up the air inlet pipe 302. The spring 308 is pushed open by the gas, and the gas enters the airbag 201 through the filter element 307. The airbag 201 swells up after being pressurized and fits the outer wall of the skin. When the air inlet pipe 302 is finished being blown, the spring 308 squeezes and pushes the valve core 304 to close the opening of the valve seat 303 through its own elasticity, thereby avoiding leakage of the gas inside the airbag 201. The one-way flow structure makes the use process convenient.

[0061] When an external force acts on the spring 308, the spring 308 undergoes elastic deformation, and the molecular structure of the spring 308 is rearranged to absorb the energy transmitted by the stress, causing the spring 308 to deform. In this process, the spring 308 will store elastic potential energy, and this energy is stored inside the spring 308 in the form of deformation, so that it can store energy without causing permanent deformation. Once the external force is reduced or removed, the spring 308 begins to release the stored elastic potential energy and returns to its initial state by restoring its original shape, that is, elastic recovery. The elastic recovery of the spring 308 follows Hooke's law, which states that the elongation or compression of the spring 308 is proportional to the external force. When the external force is reduced or disappears, the spring 308 will automatically and quickly restore its original length in proportion. The elastic contraction and reset of the spring 308 is achieved by storing the elastic potential energy caused by the deformation applied by the outside in the spring 308. Once the external force stops, the stored energy in the spring 308 will restore it to its original state.

[0062] Through the bellows structure, the upright air inlet pipe 302 can be bent and stored in the through groove 203, which is beautiful as a whole and avoids the problem of different wrists of different people and inability to effectively adapt. The mouth of the bowl is adaptively adjusted to meet the needs of different people and is flexible to use.

[0063] The steps for preparing the core of labor protection gloves are as follows:

[0064] S1: Use polyester fiber, cotton, and nylon materials as raw materials for the glove core. Polyester fiber, cotton, and nylon materials have the characteristics of softness, moisture absorption, and breathability. Cut and pre-treat the selected raw materials to meet the size and shape requirements of the glove core. Use a sewing machine to sew the cut materials into the internal structure of the glove core. Coat the interface of the inner wall with hot-melt latex, and let it stand to cool and form, so that a cold medium can be reflected during cooling and forming, thereby shortening the cooling and forming time.

[0065] S2: After the glove core body 100 is formed, one end is adhered to the hot-melt anti-skid rubber compound, impregnated, and cooled to form. One or both sides can be impregnated as needed to increase the friction with the surface of the object when gripping it, thereby improving the anti-skid property.

[0066] S3: At the same time, the adhesive material is coated on the inner wall of the wrist opening 103, and the mother Velcro is adhered for the adhesion of the child Velcro. The outer wall of the airbag 201 is adhered to the mother Velcro through the child Velcro, and the airbag 201 is flexibly attached to the wrist strap. It is worth noting that when the bowl mouth is hemmed, pure cotton cloth is used, and the rubber band 202 is wrapped inside the pure cotton cloth to apply an inward tightening elastic force to the wrist opening 103. The cotton edging causes less wear on the skin and has good breathability.
